It's always fun till someone gets hurt

With spring in full swing, many of the adult male sea lions have migrated away looking to mate. This leaves lots of young males playing "King of the Dock" and porpoising to hone skills that they will need later in life when they too swim south in search of adult females.

One of the remaining adult males appeared to be testing the mettle of a small pup by barking in the baby sea lion's face. 

Another subadult was seen with ocean litter entanglement on around his neck, which he continually scratched at. Sea lions tend to scratch like doges and have three claws on their back flippers.

The Sea Lion Center alerted the Marine Mammal Center to the entangled sea lion and yet another adult male with a flipper injury. 
The average life span of a California Sea Lion is 20–25 years.
Sea Lions are considered “opportunistic feeders,” eating available prey rather than one species.
